/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56008.348032 0.000509 0.14844 0.01136 0.98864 0 17.13553 0.46929 15.40622 0.42190 2.54367 0.18178 2.28502 0.16330 56008.348987 0.000446 0.16116 0.01228 1.00000 0 18.04461 0.51882 16.22465 0.46643 2.90816 0.20514 2.61474 0.18443 56008.349844 0.000411 0.18098 0.01411 0.97183 0 17.50145 0.53082 15.85789 0.48097 3.16743 0.22758 2.86997 0.20620 56008.350700 0.000446 0.15888 0.01265 0.98701 0 17.87255 0.51476 15.99777 0.46072 2.83951 0.21075 2.54495 0.18884 56008.351675 0.000530 0.13810 0.01050 0.99454 0 17.78661 0.47115 15.91100 0.42143 2.45641 0.17510 2.19558 0.15651 56008.352601 0.000396 0.18248 0.01425 0.98540 0 17.90527 0.54810 16.07365 0.49200 3.26741 0.23480 2.93375 0.21079 56008.353481 0.000483 0.14775 0.01139 0.99401 0 18.10582 0.49828 16.16254 0.44477 2.67512 0.19269 2.38869 0.17210 56008.354407 0.000443 0.17820 0.01399 0.98693 0 16.31818 0.49373 14.66244 0.44360 2.90790 0.21063 2.61579 0.18947 56008.355347 0.000498 0.14375 0.01104 1.00000 0 17.74958 0.48204 16.02778 0.43526 2.55154 0.18332 2.30265 0.16544 56008.356742 0.000897 0.16612 0.00919 0.98710 0 17.02043 0.35238 15.36074 0.31800 2.82742 0.14499 2.55084 0.13079
